To all whom it may concern: I

Be it known that I, CHARLES E. Qanwoon, a citizen of the United States, residlng at Pasadena, in the county of Los Angeles and State of California, have invented new and useful Improvements in Wave-Engines, of which the following is a specificatlon.

My object is to make an lmproved wave engine and my invention conslsts 1n the novel features herein shown, descrlbed and claimed. 1

Figure 1 is a to plan view showmg a shore, a pier exten mg'outwardly from the shore, and a wave englne embodying the principles of my inventlon mounted upon the pier, the view being taken looking in the direction indicated by the arrow 1 1n Flg. 3.

Fig. 2 is an enlarged top plan new of a portion of the wave engine, parts of the pier being broken away.

Fig. 3 is a sectional elevation on the line 33 of Fig. 1 and looking in thedirection indicated by the arrow 3 in Fig. 2.

Fig. 4 is a fragmentary sectional the lines 44 of Figs. 2 and 3.

Fig. 5 is a cross-section on the lme 55 of F1g.- 4.

Fig. 6 is a cross-sectlon on the lme 6-6 of Fi 2.

Fig. 7 is a fragmentary longitudinal section on the line 7-7 of Fig. 4.

The pier 1 is built from the dry land of the shore 2 and extends over the surf area 3 to the cross-pier 4, said cross-pler be ng substantially parallel with the shore hue and outside of the breakers. The wave engine 5 is mounted upon the central portion of the cross-pier 4 and is drlven by a flexible line shaft 6 running longitudinally of the cross-pier 4 near its center and substantially parallel with the shore llne. The wave engine 5 drives a line shaft 7 from which power may be taken for an desired purpose. The line shaft 6 may be rlven by any desired number of, rocker constructlons 8 and each rocker construction is vibrated by a float 9 resting upon the waves of the ocean, so that as the waves come and go the floats will rise and fall, thereby operating the rockers 8 to drive the shaft 6 to drive the fly-wheel 10, and the fly-wheel 10 is connected to the driven shaft 7 by a belt 11 and to a dynamo 12 by a belt 13. I

Referring to Figs. 2 and 3, the drlvmg shaft 6 is made up of sections, said sections being connected by flexible j omts 14, and the detail on a vertical line.

sections are mounted in bearings '15, said bearings being mounted upon timbers 16 built into the pier. Pivot hangers 17 extend downwardly from the lower faces of the tlmbers 16 and pivot shafts 18 are mounted in the hangers 17. A rocker construction '8 1s mounte rocker constructions 8 being substantially alike and there being any deslred number, as re uired to produce the power desired.

he details of a rocker construction 8 are as follows: A rocker beam 19.is mounted in a substantially horizontal position between two timbers 16 upon a pivot shaft '18, said pivot shaft extending through the rocker beam substantially at its longitudinal cenupon each pivot shaft 18, said ter. A lever 20 is connected to the center of the rocker beam 19, there being braces 21 and 22 extending from the lever 20 to the ends of the beam 19, and the lever 20 being mounted at an angle of about forty-five degrees relative to the beam 19 and relative to Braces 23 and 24 connect the lower end of the lever 20 to the ends of the shaft 18 to hold the lever 20 from yielding sidewise. A float 9 in the form of a flat boat is connected to the lower end of the lever 20 by a pivot 25, said pivot being located at the plan center of the float. Tanks 26 and 27 are mounted upon the float 9 on opposite sides of the lever 20 so that the tanks may be filled more or less with water or other suitable ballast to give the float the desired stability and power.

Cross-heads 28 and 29 are rigidly secured across the ends of the beam 19 and extend equal distances each way from the beamin horizontal planes and in lanes parallel with the drive shaft 6. Pul eys 30'and 31 are loosely mounted upon the section of the drive shaft 6 and a cable 32 is wrapped two or more times around the pulley 30 and one end of the cable is connected to one end of the cross-head 28 by a shock absorbing spring 33 and the other end of the cable is connected to the cross-head 29 by a turnbuckle 34. In a like manner a cable 35 is wrapped two or more times around the pulle 31, one end of the cable 35 being connected to the cross-head 29 by a shock absorbing spring 36 and the other end of the cable 35 being connected to the cross-head 28 by a turn-buckle 37, so that as the float 9 goes up and down on the waves the lever 20 will be vibrated and the beam 19 will be rocked upon the shaft 18 and the cables 32 and 35 leys 30 and 31 to rotate the'pull'eys u on the shaft 6.. The pulley. 30 is connecte to the I shaft 6 by automatic clutches 38 and 39,

and the pulley 31 is connected to the shaft 6 by automatic clutches 40 and 41. The cable 32 is wound upon the pulle m the opposite direction from the cab e 35 upon the pulley 31, .andthe clutches 38, 39, and 41 are all set to work one way and slip the other Way, so that as the beam 19 rocks underthe influence of the float 9 being raised by a wave, the cable 35 will pull the pulley 31 to rotate the shaft 6 in the direction indicated by the arrow 42 and at this tune the clutches 40 and 41 will grip the pulley 31 to the shaft 6 and rotate the shaft, and at this time the pulley 30 will bepulled backwardly by the cable 32 and the clutches 38 and 39 will slip. Ihen, on the return stroke, as the float 9 goes down, the cable 32 will re tate the pulley 30 in the same dlrection as indicated by the arrow 42, and the clutches 38 and 39 will grip thepulley to the shaft 6 and drive the shaft in the same direction.

Any form of clutch which will catch one way and slip the other way may be suhstituted for the clutches 38, 39, 40 and 41 but in Figs. 2, 4, 5 and 7 I have shown a preferred form of clutch. Clutch collars 43, 44 and 45 are fixed upon the shaft 6, said collars having flat clutching faces, and fiat clutch members 46, 47, 48 and 49 are rotatably and slidably mounted upon the shaft 6 against the flat clutching-faces of the collars 43, 44 and 45, the collar 44 having clutching faces. The pulley 31 is rotatably mounted upon the shaft 6 between the collars 43 and 44 and the pulley 30 is rotatably mounted upon the shaft between the collars 44 and 45. A hub 50 extends from the clutch member 46 and has winding faces enga 'ng corresponding winding faces upon a hu 51 extending from the pulley 31. A similar hub 52 extends from the clutch member 47' and engages a hub 53 extending from the other end of the pulley 31. The winding faces of the hubs 51 and 53 slide upon the winding faces of the hubs 50 and 52 so that when the pulley rotates forwardly the clutch members 46 and 47 will be pressed out wardly to grip the collars 43 and 44 and when the pulley rotates backwardly the winding faces will slide to release the clutch members 46 and 47 from the collars. In a like manner a hub 54 upon the clutch member 48 and a hub 55 upon the clutch member 49 are engaged by hubs 56 and 57 upon the ends of the pulley 30.

The fly-wheel 10 is connected to the shaft 6 by sprocket chains 58 and 59 running over sprocket wheels fixed upon the shaft 60 of the fly-wheel 10 and running over sprocket wheels 61 upon the shaft 6. The sprocket wheels 61 are connected to the shaft 6 as naeasos the other pulley wit twoshown in Fi Pawl wheels 62 are rigidlly fixed u on t e shaft 6. Thesprocket whee s 61 are oosely mounted upon the'shaft 6 and carry pawls .63 to engage the pawlwheels 62, so thattherotation of the shaft 6 will drive the chains in the direction of the arrow 64 and so that the fly-wheel 10 may spin the pawls 63 slipping over the pawl wheels 62. This construction allows the flywheel 10 to run steadily although the movement of the driving shaft 6 may be more or less unsteady.

. Thus I have produced a wave engine which may be mounted above the surface of the ocean, outside of the surf and breakers,

to be 0 erated from the waves to produce electricit or to drive a line shaft. If de-. sired a actory may be built upon the pier to be run directl from the lineshaft or the electricity may e conducted from the dy name to the factory or factories which may be located at various places distant from the pier.

Various changes may be made in the details of construction without departing from the s irit of-my invention as claime I c aim:

1. In a wave engine, a driving shaft, two pulleys loosely mounted upon the driving shaft, a rocker beam pivotally mounted be low the driving shaft, a cable wound around one pulley with both of its ends connected to the ends of the rocker beam, a second cable wound in the op osite direction around both of itsends con.- nected to the rocker beam, clutches connect ing the pulleys to the driving shaft oneway and slipping the other way, a lever arm connected to the rocker beam, and a float con nected to the lever arm and adapted to ride ice upon the waves; so that the driving shaft will be rotated continuously by the rise and fall of the float.

in one direction 7 2. A wave motor comprising a horizontal no I tion and to permit the pulle'ay'sto slip on the shaft in the reverse direction; rocker beams centrally pivoted belowsaid shaft under 7 said pulleys one beam to each pair of puls leys; cables in pairs wound in reverse direc tions around said pulle 5, said cables having their ends attached to t e ends of said rocker beams; a lever arm having its upper end fixed to said rocker beam and its lower end extending diagonally downward and shoreward; and floats pivotally attached to the lower end of said lever arms, said floats being adapted to rest on the water surface so as to rise and fall with the Waves thereby, oscillating the rocker beams and pullin the cables back and forth around the pu leys and thus turning the main shaft in one direction.

3. A wave motor comprising a horizontal i main shaft adapted to be mounted on a pier,

said main shaft being provided with sprocket wheels adapted to turn with it in one direction and to slip on it in the reverse direction, a countershaft mounted adjacent said main shaft said countershaft being provided with a fly wheel sprocket wheels and driving pulleys keyed thereto; chains connecting said countershaft sprockets and main shaft sprockets; pulleys loosely mounted in pairs on said shaft theends of said pulleys bein provided with clutch teeth; clutch mem ers loosely mounted on said shaft one on each side of said ulleys; said clutch member having one side pro vided with clutch teeth adapted to engage with the clutch teeth of said pulleys and the other side plane; friction collars adjustably keyed to said shaft adjacent the plane side of said clutch members, said collars havin plane sides adapted to engage with said 0 utch members; rocker beams centrally pivoted below said shaft one under each pair of pulleys; cables in pairs having two or more turns in reverse directions around said pulleys, said cables having their ends attached to the ends of said rocker beams; lever arms having their upper ends fixed to said rocker beams and their lower ends extending diagonally downward and shoreward; and floats pivotally attached to the lower ends of said lever arms said floats being adapted to rise and fall with the Waves thus oscillating the rocker beam causing the main shaft to turn in one direction.

In testimony whereof I have signed my name to this specification.
